Jose needs to memorize words on a vocabulary list for French class. He has memorized 20 of the words, which is four-fifths of th
Stella [2.4K]

Answer:

25

Explanation:

In order to solve this the easiest way you can use equivalent fractions.

\frac{4}{5} = \frac{20}{?}\\

Since 4 times 5 equals 20 we can multiply 5 times 5 to get our answer.

\frac{4}{5} * \frac{5}{5} = \frac{20}{25}

25 is the answer. But, if we couldn't have gotten to 20 through the multiplication we could use a proportion. That would look like the initial problem but instead of a "?" we would use a variable. I will use <em>t</em> for total.

\frac{4}{5} = \frac{20}{t}\\

So now we have our problem set up. The next step is to cross multiply. 4 by <em>t</em> and 5 by 20.

4t = 5 * 20\\4t = 100\\

And now we can solve it like a normal algebra problem.

\frac{4}{4}t = \frac{100}{4}\\t = 25

Either way, we get 25.

Goryan [66]
What percent of 150=6
X/100 * 150=6
/150. /150
X/100=0.04
X/100 *100/1 =0.04* 100/1
X=4
4% of 150=6

That means that for every dollar they take 4 cents from each dollar
150*4 pennies would equal 600 pennies or 6$ or 6.00
